Abstract: A method and apparatus for recognizing and synchronizing to in-band data at a multimedia device is provided. A content stream includes in-band data. The in-band data is processed and in-band data pattern data associated with the content stream are created. Metadata are attached to the event identification data. The event identification data are provided to multimedia devices which receive broadcasted multimedia content streams containing video programs with in-band data. The in-band data are processed and compared to the event identification data. If a match occurs, the multimedia device uses the metadata to perform specified actions.
